Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a benchtop separator for laboratory use. Background Technology

[0002] In laboratories, especially in battery research, it is often necessary to separate large quantities of experimental materials with varying volumes and weights. For example, when assembling coin cells to test battery performance, researchers need to use large sheets of separators manufactured in bulk and cut them to the required size using a die-cutting machine. However, during the cutting process, to prevent contamination and uneven cuts, researchers typically place a sheet of weighing paper on top and bottom of the separator. This can cause the separator and weighing paper to become mixed and stick together, requiring researchers to manually remove the separator with tweezers. This process is not only time-consuming and labor-intensive but can also affect experimental efficiency and accuracy.

[0003] Existing separators that utilize weight differences for separation, such as grain blower units and separating screens, are mainly used in agricultural and industrial production. Grain blowers separate light grain husks from heavy grains using a powerful airflow, but their size and dimensions far exceed laboratory requirements, occupying excessive space. Furthermore, their operation is complex, requiring specialized skills and experience, which laboratory personnel may lack, leading to operational inconvenience. Separating screens separate materials of different weights through screen vibration, but they are also bulky, expensive, and have fixed screen apertures, potentially failing to achieve effective separation for materials of varying sizes and weights found in laboratory settings.

[0004] The above two types of separators have low separation efficiency, especially when processing materials with small volume and weight differences, such as diaphragms and weighing paper, where effective separation cannot be achieved. Furthermore, due to limited laboratory space, neither of these two large separators can meet the laboratory's needs for small-scale separation. Utility Model Content

[0018] In one embodiment, the vibratory feeder includes:

The end of the base furthest from the support member is higher in the horizontal direction than the end of the base closest to the support member. The base has the vibrating surface formed thereon.

[0020] A baffle is provided on opposite sides of the base along the air delivery direction of the blower assembly, and forms a receiving groove with the vibrating surface.

[0021] In one embodiment, the base includes:

[0022] A transition section, connected to the support member, and the transition section being arc-shaped, for guiding airflow; and

[0023] The support portion is connected to the transition portion, and the support portion has the vibration surface, which is concave. The baffles are located on opposite sides of the support portion along the air delivery direction of the blower assembly.

[0024] In one embodiment, the rack includes:

[0025] Base;

[0026] A frame, situated on the base, and forming a receiving cavity with the base, including an air inlet and an air outlet communicating with the receiving cavity.

The frame has an opening on its side near the base.

[0027] A loading tray is movably disposed at the movable opening, the side of the loading tray facing the receiving cavity forms the loading surface, and the loading tray can be inserted into or removed from the movable opening.

[0032] In one embodiment, the cross-sectional area of ​​the rack gradually decreases from the bottom to the top.

[0033] The technical solution of this utility model forms an air duct in the frame, and the blowing component delivers air into the air duct, causing the lighter material on the vibrating component to be blown towards the carrying surface along the air delivery direction of the blowing component, thereby achieving separation based on weight difference; at the same time, the vibrating component can use the vibration surface to ensure that the material is evenly dispersed and avoids sticking together, thus improving separation efficiency; furthermore, by integrating the blowing component and the vibrating component into the frame, the spatial layout is optimized, and the functions are integrated, thereby reducing the space occupied by the equipment, reducing costs, and allowing the experimenter to complete the separation of materials simply by starting the blowing component and the vibrating component, simplifying the operation process.

[0046] In laboratories, especially in battery research, it is often necessary to separate large quantities of experimental materials with varying volumes and weights. For example, when assembling coin cells to test battery performance, researchers need to use large sheets of separators manufactured in bulk and cut them to the required size using a die-cutting machine. However, during the cutting process, to prevent contamination and uneven cuts, researchers typically place a sheet of weighing paper on top and bottom of the separator. This can cause the separator and weighing paper to become mixed and stick together, requiring researchers to manually remove the separator with tweezers. This process is not only time-consuming and labor-intensive but can also affect experimental efficiency and accuracy.

[0047] Existing separators that utilize weight differences for separation, such as grain blower units and separating screens, are mainly used in agricultural and industrial production. Grain blowers separate light grain husks from heavy grains using a powerful airflow, but their size and dimensions far exceed laboratory requirements, occupying excessive space. Furthermore, their operation is complex, requiring specialized skills and experience, which laboratory personnel may lack, leading to operational inconvenience. Separating screens separate materials of different weights through screen vibration, but they are also bulky, expensive, and have fixed screen apertures, potentially failing to achieve effective separation for materials of varying sizes and weights found in laboratory settings.

[0048] The above two types of separators have low separation efficiency, especially when processing materials with small volume and weight differences, such as diaphragms and weighing paper, where effective separation cannot be achieved. Furthermore, laboratories typically have limited space; introducing large equipment not only restricts other experimental activities but also increases equipment maintenance and operating costs. Simultaneously, operational complexity means requiring more time and resources for personnel training. Therefore, neither of these two large separators can meet the laboratory's needs for small-scale separation.

[0049] The main objective of this invention is to provide a benchtop separator 100 for laboratory use, designed to reduce the size and cost of the separator and simplify the operation process to meet diverse and small-scale separation needs in laboratories. It is understood that the benchtop separator 100 is particularly suitable for separating materials with small volume and weight variations, such as diaphragms and weighing paper.

[0050] Please see Figures 1 to 5 In one embodiment of this utility model, the laboratory benchtop separator 100 includes a frame 1, a blowing assembly 2, and a vibration assembly 3. The frame 1 has an air duct and a loading surface 131 located within the air duct. The blowing assembly 2 is located on the frame 1, and its outlet is connected to the air duct for supplying air into the air duct. The vibration assembly 3 is located within the air duct, along the air supply direction A of the blowing assembly 2, between the blowing assembly 2 and the loading surface 131. The vibration assembly 3 has a vibrating surface 3211 for carrying materials, and is used to disperse the materials on the vibrating surface 3211.

[0051] The technical solution of this utility model forms an air duct in the frame 1, and the blowing component 2 blows air into the air duct, so that the lighter material on the vibrating component 3 is blown towards the carrying surface 131 along the air blowing direction A of the blowing component 2, thereby achieving separation based on weight difference; at the same time, the vibrating component 3 can use the vibration surface 3211 to ensure that the material is evenly dispersed and avoids sticking together, thus improving the separation efficiency; furthermore, by integrating the blowing component 2 and the vibrating component 3 into the frame 1, the spatial layout is optimized and the functions are integrated, thereby reducing the space occupied by the equipment, reducing costs, and allowing the experimenter to complete the separation of materials simply by starting the blowing component 2 and the vibrating component 3, simplifying the operation process.

[0052] In this embodiment, the frame 1 is the main supporting structure of the entire device. Its internal air duct provides a flow channel for airflow, and the carrying surface 131 is used to support the lighter materials separated from the airflow. The blowing assembly 2 is mounted on the frame 1, and its outlet is connected to the air duct. It generates airflow by blowing air into the air duct, providing power for the separation of materials. The vibration assembly 3 is located inside the air duct, between the blowing assembly 2 and the carrying surface 131. The vibration assembly 3 has a vibration surface 3211 to support the materials and disperses them through vibration, allowing the materials to be better separated under the action of the airflow.

[0053] Understandably, compared to traditional equipment that relies solely on airflow or vibration for separation, this combination method can make fuller use of both forces, allowing the material to be subjected to a more uniform force during the separation process, thereby improving the accuracy and efficiency of the separation.

[0054] Please see Figures 1 to 3 In one embodiment, the vibration assembly 3 includes a support member 31, a vibratory disk 32, and a vibration drive member. The support member 31 is disposed on the frame 1 and adjacent to the blowing assembly 2. The vibratory disk 32 is connected to the support member 31 and extends along the air delivery direction A of the blowing assembly 2, and the vibratory disk 32 forms a vibration surface 3211. The vibration drive member (not shown) is disposed on the support member 31 and connected to the vibratory disk 32. The vibration drive member drives the vibratory disk 32 to vibrate, thereby dispersing the material on the vibration surface 3211.

[0055] In this embodiment, the support member 31 serves to fix and support the vibratory disk 32. The support member 31 is mounted on the frame 1 and positioned adjacent to the blowing assembly 2. This allows the vibratory disk 32 to better receive the airflow generated by the blowing assembly 2 and convert it into a force acting on the material. The vibratory disk 32 and the support member 31 can be fixed together using bolts or screws. The vibratory disk 32 extends along the airflow direction A of the blowing assembly 2, allowing the airflow to continuously and comprehensively agitate the material on the vibratory disk 32. This causes lighter materials to move along the extension direction of the vibratory disk 32 and ultimately enter the loading surface 131, improving the separation effect. The support member 31 has a cavity (not shown). A vibration drive is installed within the cavity of the support member 31 and connected to the vibratory disk 32. The vibration drive disperses the material by driving the vibratory disk 32 to vibrate. The vibration drive can be a vibration motor or an electromagnetic vibrator, etc. An eccentric wheel (not shown) is fitted onto the output end of the vibration drive. The vibration drive drives the eccentric wheel to rotate, thereby causing the vibratory disk 32 to vibrate.

[0056] Optionally, multiple vibration motors can be installed in the cavity of the support member 31. The multiple vibration motors are connected in series, which can simultaneously vibrate different positions of the vibratory plate 32, thereby accelerating the vibration efficiency. Furthermore, the power of the multiple vibration motors is equal, which makes the vibration of the vibratory plate 32 more stable.

[0057] Please see Figure 1 and Figure 2 In one embodiment, the frame 1 is provided with adjustment holes (not shown) on opposite sides, and the two ends of the support member 31 are adjustable in the adjustment holes, so that the vibrating plate 32 can adjust the tilt angle through the support member 31.

[0058] In this embodiment, the adjustment holes on opposite sides of the frame 1 provide an adjustable mounting position for the support member 31. By rotating the support member 31 within the adjustment holes, the tilt angle of the vibratory plate 32 can be adjusted. This allows the laboratory benchtop separator 100 to adjust the tilt angle of the vibratory plate 32 according to the characteristics of different materials and separation requirements, thereby optimizing the separation effect. For example, when both materials to be separated are relatively heavy, appropriately reducing the tilt angle of the vibratory plate 32 can reduce the work done against gravity when the materials move, making it easier for the relatively lighter materials to move along the vibratory plate 32, thus improving separation efficiency. Conversely, for lighter materials, increasing the tilt angle can increase the work done against gravity when the materials move, preventing the materials from being excessively dispersed and ensuring the accuracy of separation.

[0059] Understandably, to adjust the tilt angle of the support member 31, a threaded section can be machined on the support member 31, and a matching thread can be machined on the inner wall of the adjusting hole. By rotating the support member 31, it rotates along the thread within the adjusting hole, thereby changing the tilt angle of the vibratory feeder 32. Alternatively, a first through hole can be provided on the support member 31, and multiple corresponding second through holes can be provided on the wall of the adjusting hole. Bolts are passed through the first and second through holes in sequence, and then tightened with nuts. After loosening the nuts, the support member 31 can be rotated to adjust the tilt angle of the vibratory feeder 32. Once adjusted to a suitable position, the nuts are tightened again to secure it.

[0060] Understandably, the adjustable tilt angle of the vibratory feeder 32 increases the adaptability of the benchtop separator 100 for laboratory use, enabling it to better meet the needs of various experimental scenarios in the laboratory. Compared with separation equipment with a fixed tilt angle, this greatly improves the applicability and flexibility of the equipment, reduces the trouble for experimenters to change equipment when facing different experimental conditions, and improves experimental efficiency.

[0061] Please see Figure 2 and Figure 3 In one embodiment, the support member 31 has a first end and a second end perpendicular to the air delivery direction A of the blower assembly 2, and the first end and the second end are respectively inserted into two adjustment holes. The first end of the support member 31 is provided with an angle adjustment knob 311, which is used to adjust the tilt angle of the vibratory plate 32. Alternatively, the second end of the support member 31 is provided with a vibration adjustment knob 312, which is connected to the vibration drive member and is used to adjust the vibration amplitude of the vibration drive member.

[0062] In this embodiment, the first and second ends of the support member 31 are respectively inserted into two adjustment holes, allowing the support member 31 to rotate within the adjustment holes, thereby adjusting the tilt angle of the vibratory feeder 32. An angle adjustment knob 311 is located at the first end of the support member 31. Experimenters can adjust the tilt angle of the vibratory feeder 32 by rotating the angle adjustment knob 311 to meet the needs of different experimental conditions.

[0063] Understandably, the first end of the support member 31 is machined with a threaded hole, and the angle adjustment knob 311 is connected to the threaded hole via a screw. When the angle adjustment knob 311 is rotated, the screw rotates within the threaded hole and moves axially, thereby pushing the support member 31 to rotate around the axis of the adjustment hole, thus adjusting the tilt angle of the vibratory feeder 32. Alternatively, a worm gear is provided at the first end of the support member 31, and the angle adjustment knob 311 meshes with the worm gear via a worm. When the angle adjustment knob 311 is rotated, the worm drives the worm gear to rotate, and the worm gear is fixedly connected to the support member 31, thereby causing the support member 31 to rotate around the axis of the adjustment hole, thus adjusting the tilt angle of the vibratory feeder 32. Alternatively, a rack is fixed at the first end of the support member 31, and the angle adjustment knob 311 meshes with the rack via a gear. When the angle adjustment knob 311 is rotated, the gear rotates, driving the rack to move axially, thereby pushing the support member 31 to rotate around the axis of the adjustment hole, thus adjusting the tilt angle of the vibratory feeder 32. It should be noted that any structure that can adjust the tilt angle of the vibratory plate 32 by rotating the angle adjustment knob 311 can be used, and there are no restrictions here.

[0064] Furthermore, since the vibration drive is located within the cavity of the support 31, a vibration adjustment knob 312 is provided at the second end of the support 31. This knob is connected to the vibration drive to adjust its vibration amplitude, thereby changing the vibration amplitude of the vibrating disk 32. Using the vibration adjustment knob 312, researchers can adjust the vibration intensity of the vibrating disk 32 according to the characteristics of the material, ensuring optimal separation during vibration and making the material easier to disperse by airflow. Understandably, for materials that easily agglomerate, increasing the vibration amplitude can better disperse them, while for more fragile materials, decreasing the vibration amplitude can prevent damage during vibration.

[0065] Understandably, the vibration adjustment knob 312 is connected to the vibration drive component via an eccentric wheel, which is mounted on the output shaft of the vibration drive component. The vibration adjustment knob 312 is used to adjust the eccentricity of the eccentric wheel. When the vibration adjustment knob 312 is rotated, the eccentricity of the eccentric wheel is changed through a mechanical transmission device (such as a connecting rod, gear, etc.), thereby changing the vibration amplitude of the vibration drive component, and thus adjusting the vibration amplitude of the vibrating plate 32. Alternatively, the vibration adjustment knob 312 and the vibration drive component are connected via an electromagnetic device. The vibration drive component is an electromagnetic vibrator, and the vibration adjustment knob 312 is used to adjust the current of the electromagnetic vibrator. When the vibration adjustment knob 312 is rotated, the current of the electromagnetic vibrator is changed through a control circuit, thereby adjusting the vibration amplitude of the vibration drive component, and thus adjusting the vibration amplitude of the vibrating plate 32. It should be noted that any structure that can adjust the vibration amplitude of the vibrating plate 32 by rotating the vibration adjustment knob 312 can be used, and no limitation is made here.

[0066] Please see Figure 2 In one embodiment, the vibratory feeder 32 includes a base 321 and a baffle 322. One end of the base 321 is connected to the support member 31, and the other end of the base 321 extends along the air delivery direction A of the blower assembly 2 and is set at an angle to the horizontal direction. The end of the base 321 away from the support member 31 is higher in the horizontal direction than the end of the base 321 near the support member 31. The base 321 forms a vibration surface 3211. The baffle 322 is disposed on opposite sides of the base 321 along the air delivery direction A of the blower assembly 2 and surrounds the vibration surface 3211 to form a receiving groove 323.

[0067] In this embodiment, the end of the base 321 furthest from the support member 31 is horizontally higher than the end closest to the support member 31. Under the action of gravity, the material can be brought closer to the air outlet of the blowing assembly 2, thereby increasing the wind force on the material and accelerating the separation rate of different materials. The vibration surface 3211 formed by the base 321 is used to support the material. The baffle 322 is arranged on opposite sides of the base 321 along the air delivery direction A, and together with the vibration surface 3211, forms a receiving groove 323. The receiving groove 323 can limit the movement range of the material during vibration, prevent the material from scattering from both sides of the vibrating plate 32, and ensure that the material can be separated along the predetermined movement direction under the action of vibration and airflow.

[0068] Please see Figure 1 and Figure 2 In one embodiment, the base 321 includes a transition portion 3212 and a support portion 3213. The transition portion 3212 is connected to the support member 31 and is a concave arc shape for guiding the flow of air. The support portion 3213 is connected to the transition portion 3212 and has a vibration surface 3211, which is concave. Baffles 322 are provided on opposite sides of the support portion 3213 along the air delivery direction A of the blowing assembly 2.

[0069] In this embodiment, the transition portion 3212 of the base 321 is connected to the support member 31. The arc-shaped transition portion 3212 facilitates the flow of air, allowing the airflow to enter the air duct more smoothly and act evenly on the vibration surface 3211. This reduces the resistance and turbulence of the airflow when entering the air duct, improves the flow efficiency of the airflow, and thus enhances the separation effect on the material. The support portion 3213 is connected to the transition portion 3212, forming a vibration surface 3211. The vibration surface 3211 is concave, which allows the material to be better concentrated in the central position on the vibration surface 3211, receiving greater wind force compared to the areas on both sides. At the same time, it also prevents the material from entering the carrying surface 131 from the sides during vibration, thereby improving the separation effect. Baffles 322 are set on opposite sides of the support portion 3213 along the air delivery direction A of the blowing assembly 2, further restricting the movement range of the material and ensuring that the material does not fall from the sides of the support portion 3213.

[0070] Of course, in other embodiments, the cross-section of the vibrating surface 3211 can be V-shaped, which can make the material move more smoothly on the support 3213 and avoid the arc-shaped concave surface from obstructing the movement of the material.

[0071] Please see Figure 1 and Figure 2 In one embodiment, the frame 1 includes a base 11, a frame body 12, and a tray 13. The frame body 12 is disposed on the base 11 and forms a receiving cavity 121 with the base 11, and an air inlet 122 and an air outlet 123 communicating with the receiving cavity 121. An air duct is formed in the receiving cavity 121, and the air duct communicates with the air inlet 122 and the air outlet 123. A blower assembly 2 is disposed at the air inlet 122. The side of the frame body 12 closest to the base 11 has a movable opening. The tray 13 is movably disposed in the movable opening. The side of the tray 13 facing the receiving cavity 121 forms a loading surface 131, and the tray 13 can be inserted into or removed from the movable opening.

[0072] In this embodiment, the frame 1 consists of a base 11, a frame 12, and a carrying tray 13. The frame 12 is mounted on the base 11, and together with the base 11, they form a receiving cavity 121. An air duct is formed within the receiving cavity 121, and the air duct communicates with the outside through an air inlet 122 and an air outlet 123. A blowing assembly 2 is located at the air inlet 122, generating airflow by blowing air into the air duct to provide power for material separation. The carrying tray 13 is movably disposed within a movable opening (not shown), and a carrying surface 131 is formed on the side near the receiving cavity 121 to hold the separated lighter materials. The carrying tray 13 can be inserted into or removed from the movable opening, facilitating the removal of lighter materials by the experimenter. The cross-section of the carrying tray 13 is U-shaped or U-shaped to hold the separated materials and prevent them from falling. It should be noted that the opening can also be formed on the base 11, or the frame 12 and the base 11 can enclose and form an opening. The setting of the opening is not limited here.

[0073] Optionally, multiple baffles 1231 are provided at the air outlet 123 to prevent larger impurities from entering the receiving cavity 121.

[0074] Alternatively, a breathable membrane can be provided at the air outlet 123, which can also prevent larger impurities from entering the receiving cavity 121.

[0075] Please see Figure 2 and Figure 3 In one embodiment, the blower assembly 2 includes a fan 22 and a wind speed adjustment knob 21 for adjusting the wind speed of the fan 22.

[0076] In this embodiment, a support frame (not shown) is provided at the air outlet 123 of the frame 12, and the fan 22 is mounted on the support frame. The air force of the blower assembly 2 can be adjusted by the air force adjustment knob 21.

[0077] Understandably, in actual use, it is necessary to first turn on the vibration adjustment knob 312, and then turn on the wind speed adjustment knob 21, in order to begin the separation operation. It should be noted that in general, similar separation operations in laboratories require a single function and need to be performed long-term. Therefore, for the first use, after adjusting according to the actual separation effect and recording the corresponding setting, subsequent separations can be performed directly by adjusting according to the previous record, thus reducing the complexity of operation.

[0078] Please see Figure 2 and Figure 4 In one embodiment, the frame 12 is provided with an opening 124 communicating with the receiving cavity 121. The frame 1 also includes a sliding plate 14 slidably disposed in the opening 124, the sliding plate 14 being used to open or close the opening 124.

[0079] In this embodiment, the opening 124 on the frame 12 is connected to the receiving cavity 121. The opening 124 can be opened or closed by the sliding plate 14. The experimenter can open or close the opening 124 at any time according to the experimental needs. When it is necessary to add material into the receiving cavity 121, the sliding plate 14 can be opened. However, when it is necessary to maintain the sealing of the receiving cavity 121 during the separation process, the sliding plate 14 must be closed.

[0080] Alternatively, the sliding plate 14 can also be rotatably positioned at the opening 124. In this case, the opening 124 can be opened or closed by flipping the sliding plate 14. This structure is quite common and will not be described in detail here.

[0081] Please see Figure 2 and Figure 4 In one embodiment, the sliding plate 14 has a handle 141 on the side facing away from the receiving cavity 121. And / or, the frame 12 is made of transparent material. And / or, the air inlet 122 and the air outlet 123 are located on the same side of the frame 12 and opposite to the opening 124, and the air inlet 122 and the air outlet 123 are located on the upper and lower sides of the vibration assembly 3, respectively.

[0082] In this embodiment, a handle 141 is provided on the side of the sliding plate 14 facing away from the receiving cavity 121. The handle 141 makes it convenient for the experimenter to operate the sliding plate 14, so that the opening 124 can be opened or closed more easily.

[0083] Optionally, the frame 12 can be made of transparent materials such as glass or plastic. This facilitates observation by the experimenters, who can determine whether it is necessary to adjust parameters such as the tilt angle of the vibrating plate 32, the vibration amplitude, or the air volume of the blowing component 2 by observing the movement trajectory and separation effect of the material on the vibrating plate 32, thereby optimizing the separation effect.

[0084] Optionally, the air inlet 122 and the air outlet 123 are located on one side of the frame 12 opposite to the opening 124, and respectively on the upper and lower sides of the vibrating component 3. This facilitates the flow of air within the duct, allowing the airflow to better act on the vibrating component 3 and the material, thereby improving separation efficiency. Understandably, the airflow enters from above the vibrating component 3 and exits from below, ensuring the entire process proceeds vertically, avoiding a horizontal orientation and reducing the space occupied.

[0085] Please see Figure 5 In one embodiment, all surfaces of the frame 12 are made of plexiglass, and adjacent plexiglass pieces are connected by a plastic frame 15. The plastic frame 15 has grooves into which the plexiglass pieces are inserted. Furthermore, except for the sliding plate 14, all other surfaces are fixed to ensure the overall structural stability of the frame 12.

[0086] Please see Figure 1 In one embodiment, the cross-sectional area of ​​the frame 1 gradually decreases from the bottom to the top.

[0087] In this embodiment, from the bottom to the top of the frame 1, the cross-sectional area of ​​the frame 1 gradually decreases, forming a structure that is narrow at the top and wide at the bottom, providing a wider support base for the entire equipment. The center of gravity is lowered, making the equipment more stable when placed and less prone to tipping over.

[0088] Alternatively, the base 11 can be made into a solid structure. In this case, the top of the laboratory benchtop separator 100 is a hollow structure, thus forming an overall structure that is hollow on top and solid on the bottom. This further lowers the center of gravity, improves stability, reduces the need for additional counterweights, and lowers costs.

[0089] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
